An Underwater Bullet at 27,450 FPS Is Breathtaking

You may remember our friend Destin at Smarter Every Day shooting an AK-47 underwater. It was a cool experiment, but the pressure caused the aquarium to shatter, ruining what we now know would have been an amazing shot. To solve this problem, he built a sort of reverse-periscope for a Phantom camera and shot the AK-47 in a pool. The results are absolutely stunning.

The expanding bubble that chases the bullet, collapses in on itself, and then explodes outward again left us speechless. It looks almost like a nuclear bomb going off. Simply an incredible phenomenon captured perfectly at 27,450 frames per second. Amazing. [Smarter Every Day]
